BEAD FOR INVALIDSIl SPECIFICATION forming/part of Letters Patent N0.764,141, dated July 5, 1904.

Application liled August 8, 1903.

To all whom t may concern,.-

Be it known that I, GEORGE H. MILLER, a citizen of the United States,and residing at Flatbush, in the county of Kings and State of New York,have invented certain new and useful Improvements in Beds for Invalids,of which the following is a specification, such as will enable thoseskilled in the art to which it appertains to make and use the same.

The object of this invention is to provide an improved bed designed forthe use of invalids, whereby the occupant of the bed may be raised andsupported above the bed proper so as to permit of the making up of thebed and the cleaning and renovating thereof and for other purposes, afurther object being to provide a bed of the class specified which isparticularly adapted for use in hospitals and other places of thisclass; and with these and other objects in View the invention consistsin abed as hereinafter described and claimed.

The invention is fully disclosed in the following specification, ofwhich the accompanying drawings form a part, in which the separate partsof my improvement are designated by suitable reference characters ineach of the views, and in which- Figure 1 is a sectional side view of abed made according to my invention; Fig. 2, a sectional plan Viewthereof, and Fig. 3 an enlarged side view of one corner of the bedsteador frame.

In the drawings forming part of this specication I have shown a mainbedstead or frame comprising the usual corner-posts a, side bars I), andend members c, and in Fig. 2 one of the end members is shown inhorizontal section and the other in full lines.

Secured to each end of the side bars b in any desired manner is a box e,and each of the posts a is provided with inwardly-directed jaws a2,which in the form of construction shown are connected with bands orsleeves a3, secured to said posts.

Passing through each end portion of the bedstead or frame and throughthe jaws a2 is a shaft f, and these shafts are provided at each end witha gear-wheel or pinion g. In each of the boxes e is mounted a gear-wheela, each of which is provided with a short shaft 7b2, and

Serial No. 168,695. (No model.)

each of these shafts is also provided with a beveled gear-wheel h3, andone of the side bars b is provided with keepers Z22, in which is mounteda shaft z', and the ends of this shaft enter the corresponding boxes .eand are each providedwith a beveled gear-wheel 2, and these beveledgear-wheels 2 on the shaft c' operate in connection with the beveledgear-wheels ha on the short shafts k2.

rIhe corner-posts a are tubular in form, and mounted in each is arack-bar j, and each of the said posts is provided with a vertical slotand the rack-bars j' are provided with angular or curved arms jg; whichpass through the slots a4 in the posts a, and the arms f2 support asupplemental frame consisting of end bars c and side bars 7a2, and thissupplemental frame is adapted to move vertically, as hereinafterdescribed, and secured thereto is a sheet m, of canvas or other strongfabric.

One of the short shafts h2 is provided with a crank 0, by means of whichthe supplemental frame, which is connected with the rack-bars j, may beraised or lowered whenever desired.

Mounted in one of the boxes e, preferably adjacent tothe crank 0, is apawl @,which operates in connection with the corresponding rackgear-wheel L, and this pawl is provided with a finger-piece p2, whichpasses through a slot r in the side of the corresponding box e and bymeans of which the pawl may be disengaged from its rack-wheel L.

Wheneverit is desired to raise the supplemental frame, the crank 0 isturned in the proper direction,and said frame may be raised into theposition shown in dotted lines at s in Fig. l, and the pawl p holds saidframe in this raised'position, and in order to lower the supplementalframe' the pawl is raised and said frame will descend, and this movementmay be regulated by the crank 0.

rIhe main bedstead or frame is provided in practice with the usualmattress 'and .other bedding t, and the canvas sheet m normally reststhereon,and the patient lies on this sheet, and whenever it is sodesired the patient may be raised into the position indicated in Fig. 1by the dotted lines s, and the bed may be made up or renovated, afterwhich the supplemental frame with the patient thereon IOO may be loweredinto its normal position, as indicated in full lines in Fig. l.

The sheet my is also provided with a center opening m2, which is closedby a lacing m3, and by means of this construction the patient may use avessel when necessary and when the supplemental frame is in a raisedposition Without being removed, from the bed.

In the form of construction shown the boxes e are bolted or screwed bothto the side bars b and to the jaws a2 on the posts a; but these boxesmay be secured to the bars only, and the said bars I) may be connectedwith the Vend portions of the bedstead in the usual or any desired Way.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

A bedstead of the usual form, comprising end portions and side bars andadapted to support a mattress and other bedding, one of the side barsbeing also provided at the ends thereof With boxes, and the corner-postsof the bedstead being hollow and provided with vertical slots, rack barsmounted in said posts and provided with arms which extend through saidslots, a supplemental frame connected with said arms and provided with acovering, transverse shafts connected With the end portions of thebedstead and extending into said boxes, a longitudinal shaft-sup port bythe side bar with which said boxes are connected and extending into saidboxes, said transverse shafts and said longitudinal shaft being gearedtogether in said boxes and pinions operating in connection with saidrackbars and geared in connection with said transverse shafts,substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of the subscribing Witnesses, this 6th day of August,1903.
